You will see more "magic" happen as you your the app. I don't know the state of app on ios but on Android, Google slowly learns about your home and office locations, it learns about stocks you search for, places you travel to, movies you search for etc. As a result of this,

- In mornings, I get the traffic to office from my home. - In evenings, I see the travel time back. - When I am visiting a different city/country, I get time, currency and weather updates. If the hotel reservation and flight reservation are in gmail, I also get the latest flight updates, the hotel checkin email etc. - I have the stocks card always on. - On fridays, I get updates on movies that are in theaters. - On weekends and on trips, I get photos of nearby places (I click a lot of photos)

- I am not a sports fan but I have heard that the sports integration is decent and useful too.

Finally, - I have not used the ios app so don't know if that has all the functionality as Android. - I don't know if ios can have always-on apps or hardware shortcuts so I don't know if you can get to it with 0-taps and if it will keep the cards up to date in background.
